Verified step by step guidance1
Identify the given amount: The problem states that the intravenous bag delivers medication for 7 hours.
Identify the conversion factors: The rate of delivery is 2.75 drops per second, and each drop has a mass of 42 mg.
Convert hours to seconds: Since the rate is given in drops per second, convert the time from hours to seconds using the conversion factor 1 hour = 3600 seconds.
Calculate the total number of drops: Multiply the total time in seconds by the rate of 2.75 drops per second to find the total number of drops delivered.
Calculate the total mass of medication: Multiply the total number of drops by the mass per drop (42 mg) to find the total mass of medication delivered in milligrams.
